Smartphone-linked ear cleaner. This is a Don Quijote product that allows you to clean your ears while checking the screen of your smartphone. My family bought it, but since it links with a smartphone app, they ended up going to the ENT doctor because they changed smartphones. I asked if anyone in the family would use it, but it became unnecessary because they were going to the hospital. It's unopened, but it's been stored at home, and I haven't checked the compatible OS. It seems to be rechargeable via Type-C. - Model Name: DK-EEARW-BK (BLACK) - Compatible OS: iOS, Android - Input Voltage: DC 5V - Charging Port: Type-C - Size: 130mm x 18mm - Weight: 18g - Lens Size: 5 million pixels The box was slightly torn while checking if it was unopened, but it remains unopened. Please refrain from purchasing if you are sensitive.
